Machinist Clamps....Meet the Family Mark Presling 2022-10-20 | #shopmadetools I recently purchased a set of laser cut steel frames to make some machinist clamps in two different sizes. Other YouTube channels have covered the topic of making the clamps so in this video I wanted to discuss the materials I have used (and why) and how I went about modifying the design to make a miniature set. The original laser cut parts were purchased from D. Gray Drafting and Design d-gray-drafting-and-design.myshopify.com Doug can supply the complete kit or just the steel frames.

#RoughCut2022 - How To Set Lathe Tools - Like a Boss! Mark Presling 2022-09-30 | #roughcut2022 #SHOPMADETOOLSDear Viewers, here is my contribution to the RoughCut2022 video hashtag.It's not a cutting tool but it will help you if you do use lathe cutting tools.Enjoy!For anyone who might want to make one of these tools, I am sharing the link to a PDF version of the 2D drawings, dropbox.com/s/obza2844i2pzcqe/Tool%20Setter.pdf?dl=0Some people have asked if I intend to make any of these for sale but the short answer is no. It would cease to be a hobby for me if I were churning out batches of small parts and the reality is that I would lose money on every one I sold.
Pattern Removal Tools for the Home Foundry Mark Presling 2022-09-17 | Removing patterns from sand moulds is not without it's challenges. Especially for people like me with less than steady hands. In this video I show two methods for removing patterns with some mechanical assistance. Using these methods helps to avoid the situation where you may brush the edge of the sand mould cavity with the pattern which often affects the size and quality of the finished casting.
DIY ART DECO WALL SCONCES (THATS A WALL LIGHT FITTING) Part 7 Mark Presling 2022-08-19 | #DIY #artdeco #metalworking #lighting In this final episode of the Art Deco Wall Sconce build I assemble the glass tubing which forms the diffuser and decorative glass screen around the 450 lumen LED light bulbs. 3D printed jigs and formers hold the individual glass tubes in place until they are inserted into the electroplated brass frame. I also update the world map in this episode and thank you to all the people who sent in their own personal location for the map.Check out the playlist here youtube.com/playlist?list=PLbPzkHRZCQB_upvznHKunUXT4Yr4aY_0h
DIY ART DECO WALL SCONCES (THATS A WALL LIGHT FITTING) Part 6 Mark Presling 2022-08-07 | #DIY #artdeco #metalworking #metalpolishing #electroplating In this episode I complete all the electroplating on the brass parts for the wall lights. I am using a nickel cobalt finish because it is a very close match for the colour of chromium plate which is very difficult to achieve in a home workshop. Chromium is a dangerous and toxic metal but nickel cobalt is much more user friendly. I purchase all my plating products from Jane Kits https://janekits.com.au/jane-kits-products/ (not a sponsor)Check out the playlist here youtube.com/playlist?list=PLbPzkHRZCQB_upvznHKunUXT4Yr4aY_0h
DIY ART DECO WALL SCONCES (THATS A WALL LIGHT FITTING) Part 5 Mark Presling 2022-07-27 | #DIY #artdeco #metalworking #metalpolishing In this episode I make some last minute changes to the design of the decorative caps on the top and bottom of the wall sconces. These changes were to mitigate some problems that I may have had with the electroplating of the finished parts. With that out of the way I am able to get the brass castings polished and ready for the nickel cobalt plating process which will be detailed in the video after this one. Check out the playlist here youtube.com/playlist?list=PLbPzkHRZCQB_upvznHKunUXT4Yr4aY_0h
DIY ART DECO WALL SCONCES (THATS A WALL LIGHT FITTING) Part 4 Mark Presling 2022-07-20 | #DIY #artdeco #metalworking #metalcasting In this episode I make the four decorative brass castings which form the most important design feature of these art deco lamps. Things did not exactly go to plan although I did manage to get the result that I was looking for. I was also able to get the machining completed so these elements are now ready for polishing and electroplating.

DIY ART DECO WALL SCONCES (THATS A WALL LIGHT FITTING) Part 3 Mark Presling 2022-07-06 | #DIY #artdeco #metalworking In this episode I fix some Bozo errors from the last episode and make a start on the polishing process for lots of brass parts. I also make the first of the epoxy/sand cores for the decorative castings which will be the subject of the next instalment. Check out the playlist here youtube.com/playlist?list=PLbPzkHRZCQB_upvznHKunUXT4Yr4aY_0h
DIY ART DECO WALL SCONCES (THATS A WALL LIGHT FITTING) Part 2 Mark Presling 2022-06-26 | #DIY #artdeco #metalworking In this episode I make a start on the fabricated brass assemblies that cover the ends of the light fitting. As well as protecting the interior of the light, they are also decorative and as such need to be accurately fabricated and capable of taking a high surface finish so that the electroplated surface looks flawless. Certainly challenging and not without it's brush with Bozo!Check out the playlist here youtube.com/playlist?list=PLbPzkHRZCQB_upvznHKunUXT4Yr4aY_0h
New Fabrication Project - All the Good Stuff! Mark Presling 2022-06-18 | Hi makers. This is episode #1 of a new multipart workshop project. I can't tell you what it is because it will spoil my carefully crafted introduction. However it's got all the good stuff, casting, fabrication, electroplating, CNC and manual machining, but, no SODDERING; alright. Because, there's no such thing!Enjoy!

Enjoy! You can find out more about F1 in Schools at rea.org.au and f1inschools.com
How to Safely Drill Holes in Sheet Metal Using a Twist Drill Mark Presling 2022-04-23 | Drilling holes in sheet metal can be dangerous due to the tendency for the material to spin uncontrollably or to climb up the drill bit unexpectedly. This can lead to severe hurty hurty! Often the hole will be distorted and the edges of the hole can be heavily burred. In this video I will demonstrate how to use a common or garden variety drill bit to safely drill neat and accurate holes in sheet metal. It works on any type of metal and some rigid plastics.

The Taipan Tyro - A 50 Year Old Model Engine Restoration - Part 2 Mark Presling 2022-04-09 | In this second episode of the Taipan Tyro model aircraft engine restoration I complete the finishing processes on the remaining parts and test run the engine. We'll be doing some surface finishing, anodising, zinc plating and laser cutting. All the good stuff! Enjoy.
The Taipan Tyro - A 50 Year Old Model Engine Restoration Mark Presling 2022-04-02 | The Taipan Tyro is an Australian made, 1.9cc model diesel engine designed and manufactured by Gordon Burford in South Australia. It was the first model aircraft engine I owned and it has sat in a box for the last 40 or so years. I only found it recently and decided it would be good candidate for a restoration. In this video I discuss the history of Taipan engines, I dismantle, clean and inspect the engine and begin restoring some of the parts. I also visit Colin Maybury who helped with with fuel for this engine and the Titan engine (my previous engine series). The book featured in this video can be found using the ISBN number 9780646524986
The Titan Engine - Final Details - Its Done! Mark Presling 2022-03-26 | In this episode I am able to complete the decorative finishes on the engine such as the anodising, zinc plating and nickel plating. There are links in the video to my "Metal Finishing with Mark" playlist which includes videos with more details on each of these processes. youtube.com/watch?v=O2JgRoH6mdQ&list=PLbPzkHRZCQB99EEakSiM--TSsOJyQMaqeThe engine gets it's final rebuild and now it's off to California in the USA where it will be returned to Roger Taylor who sent me the kit back in July 2021. Huge thanks to Roger, Colin Maybury for supplying the fuel and general good advice on engines, Tony Lurie for his contacts in the aeromodelling world, Tom Lipton for advice on lapping, the guys at Home Shop Machinist Magazine and of course to George Genevro, the designer of the engine.

Metal Finishing Processes on the Titan .60 Engine Mark Presling 2022-03-12 | Now that I know the Titan engine is a runner I have stripped the engine down in preparation for some decorative and protective metal finishes. In this episode I demonstrate the process of parker phosphate for the steel propeller driver and bead blasting for some of the aluminium parts. Both these processes are easy to do in the home workshop but they make help to make your parts look more professional and parker phosphate is a durable and rust resisting coating for steel and iron parts.You can purchase the glass bead media in Australia from Supercheap Auto (#not a sponsor) https://www.supercheapauto.com.au/p/blackridge-blackridge-sand-blasting-grit-glass-bead-10kg/385733.htmlCheck out Stevie GTR's YouTube channel here youtube.com/channel/UChs2y-9lONsetwZCbowUhqgAnd Cà Lem here youtube.com/c/C%C3%A0Lem/videos
Running the Titan .60 Glow Plug Engine #17 Mark Presling 2022-03-05 | The Titan .60 is now ready to attempt the maiden start. In this video I will show some of the steps used to prepare the engine and the method I am going to use to start it. *SPOILER ALERT*If you want to skip ahead to the first start attempt go here: 07:45If you want to skip ahead to the actual start and run go here: 17:16If you are interested in the book , here are the details "Skunk Works: a Personal Memoir of My Years at Lockheed: A Personal Memoir of My Years of Lockheed"ISBN-10 : 9780316743006ISBN-13 : 978-0316743006
Building the Titan .60 Glow Plug Engine #16 Mark Presling 2022-02-23 | Well, fellow model aircraft enthusiasts, the Titan .60 has passed through the manufacturing stage and is now ready for final inspection and reassembly. Sadly, you won't get to see the engine run today but in the next episode we will attempt to start and run this lovely retro example of 2 stroke internal combustion engineering design. In today's episode I take care of the final details including manufacturing some hex headed engine mounting bolts from real aircraft bolts.
Building the Titan .60 Glow Plug Engine #15 Mark Presling 2022-02-16 | In today's episode I fix the issue with the overbalancing display stand, machine the spraybar, needle valve and the needle valve cap. Most of the major components are now done and the rest is going to be cleaning, metal finishing and reassembly. Getting close now!
Building the Titan .60 Glow Plug Engine #14 Mark Presling 2022-02-07 | While I am waiting for some tools to make the spraybar and needle valve for the Titan I decided to go ahead and make a display/running stand and the fuel tank. The tank is fabricated mostly from aluminium and is probably way over engineered but it was fun to make and I got to practise some unusual single point threading techniques. The display/running stand is a replica of the one detailed in the build notes but I have decided not to use it to run the engine since it will almost certainly get fuel all over it.
Building the Titan .60 Glow Plug Engine #13 Mark Presling 2022-01-25 | In this video I spend several hours setting up to drill a single hole in the crankshaft and a single hole in the crankcase. The hole in the crankshaft forms a simple rotary valve to admit fuel and air into the crankcase and it must line up accurately with the inclined hole in the venturi. Several jigs and tools were required to ensure accuracy of the position of that hole.The second hole forms the bore for the spraybar and it must be positioned exactly on the centre line of the venturi hole in two planes. Spoiler alert....it was a success!You can check out Jay Miller's channel here youtube.com/channel/UCpvK3sWUvzutP_5aG-fohGQ/featured
Building the Titan .60 Glow Plug Engine #12 Mark Presling 2022-01-19 | In this video I heat treat the partly machined piston before carrying out the final sizing to fit the cylinder liner. This process is called normalising and it helps to ensure that any residual stresses in the cast iron piston are relieved. I used my metal casting furnace to bring the part up to a dull red heat and the residual heat in the furnace prevents the cast iron from chilling and going so hard it cannot be machined. I also tackle the machining of the venturi in the forward end of the crankcase. This required some tricky fixturing to ensure the cast venturi could be turned on the lathe with the fixture attached to the faceplate. I have also been able to contact the current owner of the Titan patterns from which new castings could be made. Enjoy!
Building the Titan .60 Glow Plug Engine #11 Mark Presling 2022-01-08 | In this video I machine the final version of the piston in cast iron. We also discuss the reasons for using cast iron rather than the much lighter aluminium piston I made as a practice part. I have another accessory for my welding bench socket and I share a problem I had with my TouchDRO setup on the Bridgeport mill. Don't worry, it gets resolved and I am back in love with my TouchDRO.
How to Add a Digital Readout to a Lathe Tailstock Using a Cheap Caliper Mark Presling 2021-12-31 | I have a job to do on my Colchester Student Lathe that requires a drilled hole to be held to very tight tolerances. Older style Colchester lathes have rounded castings which make it difficult to mount an indicator on the top of the tailstock casting. Also, I don't own any indicators with travel greater than 25mm. Mounting a cheap digital caliper to the tailstock quill and casting is not new but it's especially challenging to do on a Colchester. This is my solution to the problem.
Building the Titan .60 Glow Plug Engine #10 Mark Presling 2021-12-17 | In this video I finish the connecting rod. It was partly machined on my little Sieg X3 CNC milling machine, until the PC which drives the mill gave up the will to live and the remaining ops had to be completed on the Bridgeport and the Colchester lathe. I also detail the prototypes for the piston and give you a sneaky preview of how the engine will sound during starting. For more information about the Joe Martin Craftsmanship Museum craftsmanshipmuseum.com
Building the Titan .60 Glow Plug Engine #9 Mark Presling 2021-12-07 | In this video I finish the second ops on the Titan Glow Plug engine cylinder head. I also complete the machining on the propeller driver. This involves some old school machining, fixturing and some of that new fangled CNC machining. I also do a mini workshop tour showing some new tools and modifications to existing infrastructure to make the workshop experience just that little bit better.
Building the Titan .60 Glow Plug Engine #8 Mark Presling 2021-11-26 | Despite early promises to machine the remaining details in the cylinder head I don't actually get to those things. However, I do get the steel propeller driver and the aluminium alloy spinner completed. These two items make the engine look much sexier! I demonstrate the use of the Turnado freehand turning attachment with the tracer arm attached (#not a sponsor). This handy tool made my life much easier and the semi elliptical profile turned out much more beautifuller than I could have imagined (is that a word?)Enjoy
Building the Titan .60 Glow Plug Engine #7 Mark Presling 2021-11-16 | In this episode I mill the ports in the cylinder liner, machine the first stage of the cylinder head and finish most of the cooling fins which get shrunk onto the cylinder liner. This probably marks the half way point of the build. Enjoy!
Building the Titan .60 Glow Plug Engine #6 Mark Presling 2021-11-10 | In this episode I machine the cylinder liner for the Titan engine. I also demonstrate the use of a shop made expanding internal lap used to size and polish the bore of the liner. Watch as I make my usual blunders in terms of tool selection and technique but like all good stories, there's a happy ending!
Building the Titan .60 Glow Plug Engine #5 Mark Presling 2021-11-02 | In this episode of building the Titan .60 model glowplug engine I machine the rear crankcase cover which also doubles as the engine mounting. It is mostly lathe work, a little milling and some CNC drilling operations. A big thankyou must be extended to Craig of Craig's Workshop who invited me on a shop tour at his house in Tasmania. Also Bill AKA Bill Baggins on YouTube, who gifted me a beautiful hand made knife. And sticker contributors, Nigel from Go Create Hobby Machine Shop youtube.com/c/GoCreateHobbyMachineShop, Jon from Black Knight Customs youtube.com/channel/UCVjz3XDNu4etto7pjL35rTg and Gary from Eccentric Engineering https://www.eccentricengineering.com.au/You can skip straight to the Titan content at 5:04
New Life for Older Machines. How to upgrade to CNC without learning G-code. Mark Presling 2021-10-16 | Recently I was invited to visit the workshop of a Brisbane based entrepreneur and maker named Sean McGrade. Sean is developing a system which allows owners of manual milling machines to upgrade to CNC operation without having to post G-code. The system operates from a tablet, wirelessly and is capable of high precision, even on worn machines without ball screws. In this introductory video we get to take a look around Sean's workshop, see some sample parts made with the system and watch a complex part being made. For more information or to register your interest you can check out this linkmaharn.comAlthough initially called Whatbox, that was just a working title. The name of the system at release will be called Maharn.It's important to note that this is not a paid promotion. I have and interest in CNC machining and old Bridgeport milling machines so I accepted Sean's offer to take a look around his workshop and document what I saw and how I felt about the system he is developing. There will be follow up videos at a later date.
Building the Titan .60 Glow Plug Engine #4 Mark Presling 2021-10-01 | In this episode I demonstrate how I made a simple external lap from aluminium bar stock. With the lap and some 5 micron diamond lapping compound I was able to remove the last few hundredths of a millimetre from the semi hardened 4140 steel crankshaft journal and also to correct some taper in the crankshaft. The result is a vast improvement on the previously turned finish and it also allows for accurate control over size and the eventual fit.
Building the Titan .60 Glow Plug Engine #3 Mark Presling 2021-09-24 | In episode 3 of the Titan Engine build I rectify some errors (painful to admit) and complete the machining of the crankcase exhaust port and the bronze crankshaft bush.
Building the Titan .60 Glow Plug Engine #2 Mark Presling 2021-09-17 | In this episode I will be demonstrating some set up techniques for accurately machining some difficult features on the Titan engine crankshaft and crankcase. The crankcase is particularly difficult since it has very few accessible datum features so some simple tools and fixtures are required to allow for indicating the previously machined bores.
Building the Titan .60 Glow Plug Engine #1 Mark Presling 2021-09-10 | The Titan is a .60 cubic inch or nearly 10cc model aircraft glow plug engine designed for methanol based fuel. The kit comprises several aluminium castings and bar stock. It was designed as a final year project for engineering students and was put together by George Genevro, a professor of Industrial Technology and supplied to me by Roger Taylor from California USA. Join me in a journey to machine this engine. In this first episode I detail the components of the kit and make a start on machining the crankshaft from a single piece of 1018 steel bar stock.
#ShopMadeTools - Why? Mark Presling 2021-09-04 | #shopmadetoolsWhy do we make shop made tools? Often it's because an off the shelf tool that you might purchase won't fit your machine or it has inherent limitations that make it unsuitable for your application. In this video I will show you two shop made tools that have allowed me to extend the range of operations I can carry out in my shop.

How to Powdercoat Awkward Parts DIY Mark Presling 2021-07-17 | #powdercoating #outdoorlightingPowdercoating at home can be quick and simple but some parts are harder to do than others. The dreaded "Faraday cage effect" can make it very difficult to get the powder to adhere to internal corners and deep pockets. In this video I demonstrate a method which worked for me. Full credit must go to Stuart from the YouTube channel Scrounga's Workshop. Stuart kindly suggested a workaround that is simple and effective.
Absolute Beginners Guide to Decorative Glass Mark Presling 2021-07-10 | Glass is a wonderful material to add to your DIY projects. You may think it's sterile, unyielding and hard to work with but it can be processed into highly decorative forms. In this video I explore two different techniques for adding a decorative finish. One is masking and sandblasting and the other is called Glue Chipping. I learned about both these techniques by watching a YouTube Channel called "Happy Gilder" youtube.com/channel/UC5isMTsFMUaOR-AChVx0aVwCheck it out for some more simple and achievable techniques for working with glass.
Glass Cutting....Its Not Rocket Science Mark Presling 2021-07-04 | Here's a brief introduction to the techniques, tools and procedures for making straight and curved cuts in glass.
How to Make Multiple Castings From a Single Match Plate. Mark Presling 2021-06-27 | Got a lot of small castings to make? Well, you need a "match plate". In this episode I made 12 castings from three greensand moulds. The patterns are mounted on a double sided board and the cope and the drag can be rammed up either side of the board. I also share some revelations regarding mistakes I had been making previously and the end result was a 100% yield and no failures. Outstanding!
How to Rivet Tiny Parts Using Shop Made Aluminium Rivets Mark Presling 2021-06-23 | This is a follow on video to my last upload on how to make some DIY outdoor light fittings for the garden path. In this episode I show how I made my own tiny rivets and used them to attach the bars to the two sides of the light fitting body. Riveting is a useful alternative to welding and it can be done with relatively simple and cheap tools. It also avoids the issue of distortion and accidently melting the parts you have taken so long to make. I also use the CNC mill to manufacture the composite plastic base for the light fitting. Some lathe action too!
Some (Durable) DIY Outdoor Lighting Mark Presling 2021-06-19 | Sadly, cheap solar path lights are simply not worth the money. The light output is poor, the solar cells fail, the materials are not corrosion resistant or UV stable and they will only disappoint. Ask me how I know! In this series of videos I demonstrate how to make your own replacement outdoor lighting using good quality materials and the more reliable hard wired, low voltage option.
The MIXIE A DIY Steampunk, Backlit Digital Clock - Its Alive! Mark Presling 2021-05-19 | Well folks, this is the final episode of the Mixie clock build.
